Why your AI agent doesn’t actually remember anything

A support agent lost a billing conversation across days because it lacked history recall, showing that storage alone does not equal memory.

The piece argues that agent memory is a separate capability from correctness tools like idempotency, workflow state machines, and transactional consistency.

Real-world agents often execute isolated steps correctly but still fail because they cannot preserve, prioritize, and trust prior context over time.

True memory for agents includes persistence, selective recall, compression, decay, and contamination prevention, not just a bigger database or context window.
